I currently have a computer from which i sync my music/videos via iTunes. What happened is that this PC broke down out of the blue, and going down with it are all the data in the HDD. I'm now currently using another PC for the time being. I'm just wondering if I'm able to sync my device with a newly downloaded iTunes for the period the other computer is under repair, without overwriting the songs currently in the device?

In the event that the data cannot be recovered, is there any way i can transfer the songs currently in the device to a new computer?
